Key value for chemical safety assessment
- EC50 for microorganisms:
- 399 mg/L
- EC10 or NOEC for microorganisms:
- 20 mg/L
Additional information
The O2 consumption of the test item was determined in a ROBRA test (BASF SE, 10/1196/88, 1988). The inoculum containing 48 h old bacteria was exposed to the test item in concentrations of 10000, 5000, 2500, 1250, 625, 312.5, 156.25, 78.13, 39.06, 19.53, 9.77, 4.88 mg/L under static conditions. Based on the respiration rates the EC50 value was determined to be 399 mg/L, the EC10 was determined to be 20 mg/L and the EC90 value was determined to be 2853 mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
